The wing is designed for slow approaches and a stall speed of 65 KCAS while still offering a maximum cruise speed of 180 KTAS. The specially designed wingtips facilitate tight turns on water and provide hydrodynamic lift support in case of contact with the water surface.
The sponsons are attached to the centre fuselage section. This is an optimized design resulting in smooth water landings and short take-off runs. The sponsons houses the fuel and the main landing gear, keeping the centre of gravity at the lowest point. In addition they act as a working platform.
A true amphibian, the Seastar is at home on land as well as on water. Its wide-track landing gear ensures smooth landings on runways. The aircraft comes with a hydraulically controlled nose wheel steering system.
Equipped with 2 powerful Pratt & Whitney PT6A-135A turboprop engines, the in-line push-pull engine configuration eliminates asymmetric thrust in the event of an engine failure. Moreover, over-wing placement minimizes the possibility of Foreign Object Damage and water ingestion into the engine intakes.
The Seastar’s all-composite airframe is corrosion-free even in saltwater. Its integrated structure is designed for long structural life and high damage tolerance, reducing maintenance costs and downtime. The unique composite airframe prevents any leakage caused by rivets and bolts as commonly experienced by metal airframes.
Unlike competitors with floats, the Seastar is a flying boat. Its V-Keel shaped fuselage offers similar handling to a powerboat and allows take-off and landing in rough sea states. In flight, the integrated-hull design reduces drag force, provides greater fuel efficiency.
